A Mathematical Construction of the Axial Anomaly in the BV Formalism. (arXiv:1711.11301v1 [math-ph])
来源于:arXiv
The axial anomaly of the massless free fermion is given by the index of the
corresponding Dirac operator. We use the BV formalism and the methods of
equivariant quantization of Costello and Gwilliam to produce a new,
mathematical derivation of this result. We formalize through these methods the
conventional wisdom that the anomaly measures the failure to construct a
well-defined partition function. 查看全文>>
